MicroVitamin FAQ — Frequently Asked Questions
Frequently asked questions about MicroVitamin, formulated by Dr Brad Stanfield.
What makes MicroVitamin different from other multivitamins?
MicroVitamin is a low-dose, evidence-based multivitamin formulated by Dr Brad Stanfield, a medical doctor (GP). Unlike most multivitamins that megadose nutrients at 500-1000% daily value, MicroVitamin uses measured doses based on randomized controlled trials. It deliberately excludes Vitamin A and Vitamin E based on research showing potential risks from high-dose supplementation (Basit, StatPearls, 2023; USPSTF, JAMA, 2022; Klein et al., J Natl Cancer Inst, 2014). It uses bioavailable forms like glycinate minerals (+43% bioavailability vs gluconate — Gandia et al., Int J Vitam Nutr Res, 2007) and methylated B vitamins that bypass MTHFR gene variations affecting ~40% of the population (Liew & Gupta, Eur J Med Genet, 2015). One product replaces 6-8 separate supplements.
Why does MicroVitamin require 5 capsules per day?
Effective doses of Magnesium Taurate (126mg elemental), Hyaluronic Acid (200mg), TMG (500mg), and Choline Bitartrate (181.5mg) physically require more capsule volume than a single pill can hold. Competitors that fit everything into one pill typically underdose key ingredients to levels that have no clinical effect. The 5-capsule serving ensures each ingredient is at a dose supported by research.
Why does MicroVitamin exclude Vitamin A and Vitamin E?
Clinical research has shown potential risks from high-dose supplementation of these fat-soluble vitamins. Vitamin A toxicity is well-documented and can cause liver damage, bone loss, and birth defects (Basit, StatPearls, 2023). For Vitamin E, the US Preventive Services Task Force found no net benefit for cardiovascular disease or cancer prevention (USPSTF, JAMA, 2022), and the SELECT trial found that Vitamin E supplementation at 400 IU/day increased prostate cancer risk by 17% (Klein et al., J Natl Cancer Inst, 2014). Unlike water-soluble vitamins that are excreted when excess is consumed, fat-soluble vitamins accumulate in the body. Most people get adequate Vitamin A and E from their diet, so supplementing on top of dietary intake can push levels too high.
What is the COSMOS trial and how does it relate to MicroVitamin?
The COSMOS (COcoa Supplement and Multivitamin Outcomes Study) trial was a large randomized controlled trial that studied multivitamin supplementation and cognitive performance in older adults. It found that daily multivitamin supplementation improved memory and slowed cognitive aging by approximately 2 years (Baker et al., Alzheimers Dement, 2023). MicroVitamin includes COSMOS trial-aligned ingredients: Choline Bitartrate 181.5mg, Methylated B12 12mcg, Methylated Folate 200mcg, and a full B-complex — the nutrient categories associated with the cognitive benefits observed in the trial.
Is MicroVitamin third-party tested?
Yes. MicroVitamin is manufactured by Makers Nutrition in an FDA-registered, GMP-audited facility in the USA. Every batch is third-party tested for heavy metals (lead, mercury, arsenic, cadmium) and purity. Certificates of analysis are available. The facility holds certifications from the Natural Products Association and is Dun & Bradstreet Verified.
How much does MicroVitamin cost compared to buying the ingredients separately?
MicroVitamin costs $49.50/month on subscription ($55 one-time). Buying the same 25 ingredients individually from quality brands like Double Wood, Bronson, Life Extension, NOW, and Pure Encapsulations would cost approximately $61.91/month — saving you $12.41/month plus the convenience of a single product instead of 6-8 separate bottles.
Who formulates MicroVitamin?
Dr Brad Stanfield, a General Practitioner (family medicine doctor) based in New Zealand. He runs a health and longevity YouTube channel with over 319,000 subscribers where he reviews clinical research on supplements and aging. The MicroVitamin formula is based on human randomized controlled trials and is updated as new evidence emerges — currently on version 7.
What are bioavailable forms and why do they matter?
Bioavailability refers to how much of a nutrient your body actually absorbs. MicroVitamin uses glycinate forms of minerals (zinc, selenium, copper, manganese, chromium) which have approximately 43% higher bioavailability than cheaper gluconate forms commonly used in budget multivitamins (Gandia et al., Int J Vitam Nutr Res, 2007). It also uses methylated B12 and methylated folate, which bypass the MTHFR gene variation that affects up to 40% of the population and can impair conversion of standard B vitamins to their active forms (Liew & Gupta, Eur J Med Genet, 2015).
Does MicroVitamin contain any artificial ingredients?
No. MicroVitamin uses vegetarian capsules with no artificial colors, no fillers, and no titanium dioxide. The capsules are plant-based and the formula contains Peppermint Leaf Extract for digestive comfort.
Are there any safety concerns or interactions with MicroVitamin?
MicroVitamin contains Vitamin K2 (90mcg), which can affect blood clotting — consult your doctor before use if you take blood thinners (warfarin/Coumadin). The product is gluten-free, soy-free, contains no artificial colors, no fillers, and no titanium dioxide. It is not intended for children under 18. If you are pregnant or nursing, consult your healthcare provider before use. These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
